IMPROVEMENT IN MILK-COOLER.

The @ehefiule referred to in these Letters Patent and making part of thesame.

1'0 all whom it may concern Be it known that I, Eownv P. SPENCER, ofScott,.'

description thereof, reference'being had to the accom-v as panyingthereon. I

My invention consists of an improved apparatush be used in dairies forregulating the temperature of milk, the special feature scribed. i

Figure 1 is a top plan view, of the device with the upper pan removed.

Figure 2 is a longitudinal v apparatus complete. p

In the large' dairies, as now conducted in various parts of the country,the milk of a large number of cows is brought in at onetime, and it isdesirable to have some means of cooling the same, especially in hotweather, and also of raisipg-it'to the proper temperature in coldweather; audit is to accomplish these purposes that my invention isdesigned: I

In constructing my apparatus, 1' provide a'frame, #0; any suitable size,mounted on legs, as shown in In this frame, I placea large oblong pan orvat, B, made preferably of sheet'metal, and suspend it by a projectingrim around the edge, and, if necessary, supporting it by bars or handsunderneath.

This pan B has secured across one end,.near the top, a trough 'or pipe,S, which has a series of perforations along its entire length,'for theescape of water into the pan B, there being an opening,'R, at the top,through which the water enters from a reservoir, E, as represented infig. 2. or from any other source.

This distributing-pipe S, instead of being made in the form of a pipe,may be simply a trough, open on its upper side, and have a series ofperforations or notches along its front side or edge, for the escape ofwater into the pan B, the object being to deliver the water at pointsacross the entire end of thepan, so as to cause a current of fresh,warm, or cool water,;as the case may be, to flow evenly along the entirewidth of the pan, instead of a narrow current along the centre or oneside only, as would be the case if the supply was delivered at a singlepoint only.

By this mean s, I secure an even temperature throughout all parts of thepan, which is a very desirable object.

This pan B is provided, at its opposite end, with an escape-pipe, H, asshown in fig. 2, for the water to flow out at, and it has also in thebottom", near the same end, a pipe, G, withaeock, N, for drawing oil thecontents of the pan when desired.

. I also provide another pan, 0, of a form corresponding to that of B,except that its sides are more inclined, so as to leave .a space orwater-chamber around the sides, and under its bottom, as shown clearlyin fig. 2. There is also a water-space between the two pans B and O.

This pan 0 has alsoa pipe or tube, K, extending from its bottomdownward, and fitting snugly into the drawings, and to the letters ofreference marked ertical section of the s of which are hereinafter de-.

pain, as shown in fig. 2, the joint of these two pipes being madewater-tight, either by having what is known as a ground-joint, or bypacking it with rubber, or any suitable material. I

In the lower pipe Lithere is a cock, M, by which the contents ofthe'npper pan 0 can be drawn bit whenever desired without at allinterfering with the contents of the lower pan B. a

The upper pan G is set loosely into the lower one,

rests upon the flange of the pan B, where the latter bears upon theframe A.

If the upper pan be made very large, so that there is a liability of itsbottom sagging, it may be supported by wooden strips, placed lengthwiseunder it and resting on the other pan B, which will also serve to createa series of separate currents in the water between the two, from end toend; or it may be supported by metal straps passing crosswise under thebottom.

To the legs, at the upper or supply-end of the frame, I attach a shaft,P, or which I secure a pair of eccentries, 0, as 'shown' in iigrfi,there befiig aieverq'Q, at tached to the shaft.

. By this means, the shaft may be turned so that the eccentrics shallelevate that end of the pans, and thus cause the contents of the pans toflow to the opposite end, when it is desired to empty them.

In ordinary use, the milk is put into the pan 0, and water allowed toflow into pan B and fill the space between them.

At certain seasons, when it is not necessary to alter the temperature,both pans may be used for holding the milk, the pan 0 being removed andused sepa rately.

A table, D, may be attached, for supporting the water-reservoir E, whenit is necessary to use the latter, but where a running stream or supplyof water exists, these may be'dispensed with and the water conducted atoncein'to the trough S.

Having thus described my invention,

What I claim, is---- 1. The combination of the pan B, provided with thedistiibutingtrough. S and the pan 0, arranged to operatesubstantially asdescribed.

2. The pan 3, provided with the escape-pipe H,

emptying-pipe G, and pipe L, the two latter being provided with cocks,substantially as and for the purpose set forth. 3. In combination withthe pans B and(], constructed as set forth, the frame A, provided withshelf D and the eccentrics 0, arranged to operate as herein described.

4. In a milk-tempering apparatus, the distributingpipe or trough S, soarranged as to deliver the inflowing water at points across the entireend, or nearly so, of the water pan, substantially as herein described.
